To all whom it may concern:

ile it known that I, MA'rrIiEW li. Kom.- nAUscn, a citizen of the United States, residing at llillerica, in the county of Middlesex and-Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Machines for Securing Cloth, of which the following is a specification.

My invention relates to machines for scouring cloth and comprises a series of laterallyadjaeent tanks with submerging rollers, arranged in each tank, and a carrier-roll and squeeze-rolls, common to all said tanks, and guides, arranged to conduct the cloth from each tank to the next tank, to pass thc cloth -successively through all said tanks without intermediate handling, and consists in the devices and combinations hereinafter described and claimed.

' In the accompanying drawings, Figure i is a front elevation of a machine constructed according to my invention; Fig. 2, a left end elevation of the same; Fig. 3, avertical section of any one of said tanks at right angles to its rolls and in the same plane a section of all the rolls and guides; Fig. 4, a plan of said machine, omitting the driving gearing.

In machines for scouring cloth or washing cloth, morepsrticularly woolen cloths, tetree them from irt and grease in the wool or received during the process et manufacturing, it is customary to run the cloth l through varions waters and solutions of soaps and alkalies, each water or solution being contained in a separate tank or receptacle and the cloth requiring to be coiled and uncoiled each time it is changed from one tank to another, the cloth being laid in a heap or coil in the bettom of one tank and drawn back and forth 4e through squeeze-rolls a suiiieient number of times and deposited upon the lloor or upon a suitable rack or table or iu a suitable receptaele and being then placed in another tank containing a different solution ot -water of a different temperature and again passed repeatedly through squeeze rolls, there being a pair of squeeze-rolls te each tank, and so on successively through all the required number of tanks. Or, more commonly, a single tank 5e is used and after passing the cloth a sulliclent number of times through the tank, the

water or liquid ln the tank'is emptied and sont s.. 424.149. on mano the tank iiiled with water of a diITerent temperature or with a different solution and the cloth is again passed through the same tank,

the tank requiring to be emptied and iilled A as man y times as there are different waters or solutions used, much time being required in. the iilling and emptyingof the tanks and the in troduction of the cloth between the squeezerolls. 'ihe cloth during the scouring is gathered laterally into the form of a string.

My improvement saves time, avoids waste of the scouring solutions, saves labor and also floor-space, in cases where a separate tank is used for each water or solution.

In the drawings A represents a long tank divided by vertical transverse partitions o into a series of laterally -adjaeent smaller tanks u', cach water-tight with respect to the adjacent tanks. lu cachot the tanks a' are arranged twosninnerging-rollers b b', near the bottom oi said tank and near the rear andfront of said tank, each of said submerging rollers being supported at each end by n studplate B bolted to one of the partitions a or to the ends a* of the large tank A, as indicated at b in Figs. 1 and 3 and each stud-plate having a central lateral projection I which enters a correspondingv depression b* in the adjacent end of the submerging roller supported thereby, to support the submerging rollers in a horizontal position and to allow them tobe rotated by the friction of the cloth C. A earrier-roll I) may be arranged immediately above the front row of submerging-rollers b',

and extended over all the small tanks a and may have its bearing in half-round notches or half journal-boxes cut in the tops of the partitions aand end-pieces a', said carrierreii having annular grooves d, to receivesaid partitions and end-pieces, the bottoms ot said grooves forming the journals of said carrierrolls.

'lhe horizontal squeeze-rolls E E extend above all the tanks n.' and are supported in ystout pe'destals or pillow-blocks F F bolted,at ff, to the iloor of the apartment in which the machine stands, the upper squeeze-roll E being supported in sliding-boxes f' f, the squeezing action of said rolls being, as usual, due to the weight of said upper squeeze-roll. The squeeze-rolls are preferably grooved at f 3 above each partition u and cud-piece u'-, te

r the machine so raised away from t i5 to the prevent li uid from one tank, when pressed outof thee oth, from runningon said rollsand dropping into another tank or on to tho floor. The shaft e of the lower squeezeroll has fast 5 thereon a gear e' engaged by a pinion e fast on the hub of a driving-pulley (i, the latter being driven from any convenient motor to impart a rotary motion to the lower squeezerol a loose pulley G' being arranged in the xo usual manner concentric with the pulley G, to receive said belt when the machine is not running, said pulleys G G turning on a' horizontal stud gsupported by a bracket g bolted to the pillow-block at one end of The upper squeeze-roll is driven from the lower by means of gears f of equal size, faston the shafts of a squeeze-rolls respectlveiy and engaging each other. The u o. lower ueeze-roll by means of chains or wire ropes t h', attached to the sliding boxes f' f and passing over grooved idle-pulls s h' h and on to other grooved pulleys h t, fast on the shaft Il, said .a5 shaft ll being rotated byahand-wheel h and bei ng su h", bolt shown in Figs. secured one or more ratchets h" hl,

ported in suitable journal-boxes h7 tothe front of the large tank A, as 1 and 2. To the shaft ll is adapted 3o to be held from rot'ation by pawls h" h", pivoted on the endieces a to prevent the chains or ropes h from unwinding-and to hold the squeeze-rolls out of contact when desired to introduce work into the machine or to take up slack places in the cloth which might otherwise allow the cloth to be wound around the squeeze-rolls.

Between the squeeze-rolls and the carrier' roll is arranged a guide I,consisting'of asuit- 4o able rectangular frame l', provided with ears i', adapted to be bolted to the end-pieces a',

and consisting also of vertical parallel guidebars t", the s between said bars guiding the cloth in ts passagefrom the carrier-roll ueeze-roll. l

The oth is introduced into the machine through a tension-piece J ,similar in construction to the guide I and having a framej and vertical parallel bars j', secured therein, said ;e tenslon-piece standing at right angles to the guide and on the opposltesldeof thesqueezeroll therefrom and the cloth being secured by running it on opposite sides of alternate tension-bars j'. From 5 the tension-piece the cloth passes over a grooved roll K, journaled above the back of the tank,down under the submerging-rolls over the carrier-roll D, through the guide! and between the squeezo-rolls, then down nno der the submerging-rollers, over the carrierroll, through the guide and between the sqtoezerolls repeatedly, the rope of cloth being guided laterally, from the carrier-roll to the squeeze-rolia, away from the end of thc per squeeze-roll may bel proper tension on the' machine at which the cloth enters, so as to pass over cach of the partitions a and to en.

ter in succession all the tanks. As the cloth,

threads; the next tank may contain an al-` kali, as soda or potash, to loosen and sap'onify the oil; the third tank may contain soap and water; the fourth, another solution of soap; the fifth, hot water to remove the greater part of the soap; the sixth, cold water; and the seventh, clear cold water which may be introduced in the form of a sheet o r spray directed upon the cloth-,1in a well known man-v 8j ner, or in acontinnous stream, the tank being provided with a suitable overflow or outlet in the usual manner.

I do not intend, however, to limit myself to any specific number of tanks,tho number varying with the kind of goods and theirtreatment during the process of manufacture.

The pressure of the upper squeeze-roll upon the lower may be increased and regulated by levers and woights,in the usual manner,such

levers and weights not heilig shown because being in common use and well understood.

l claim as my invention- 1. 'lhclcombination of a series of laterallyadjacenttanks, s'ubmerging rollers, arranged in each tank, a carrier-roll and continuous squeeze-rolls, arranged longitudinally of said series of tanks and common toallsaid tanks, and guides, arranged to deflect the cloth in its passage from said carrier-roll to said feedroll laterally and to guide said cloth from each tank to the next, as and for the purpose specified.

2. The combination of a tank, divided by vertical partitions into a series of laterallyadjacent tanks, submerging rollers, supported in each of said last-named tanks, a carrier-roll and continuous squeeze-rolls arranged longitudinally of said series of tanks and extending above all said partitions, and a guide, arranged to conduct cloth from ysaid carrier-roll above said .partitions from one side to the otherof each of said partitions, to pass such cloth successively through all said tanks without intermediate handling, as and for the purpose specified.

v In witness whereof I have signed this-specification, in the presence of two attesting witnesses, this 6th day of' February, A. l). 18592.
